What reviewers say

Tech Advisor and TechRadar praise the versatile cameras, particularly the large main sensor and detailed periscope shots, along with the screen, performance and quick charging. Both find the handset heavy and the software more complicated than its rivals, with uneven AI tools and shorter update support. Tech Advisor is pleased with battery life and often gets two moderate-use days; TechRadar finds everyday endurance less impressive. Both see the optional Photography Kit as useful for serious shooting, while noting the loss of the main camera's variable aperture.
